At Perfect Pooches, we know dogs. Whether we’re raising healthy litters, grooming all breeds, or supporting owners through our fertility services, we’ve spent years working with dogs in every condition. That means we recognise the early signs of heat stress before they become dangerous.
Heat exhaustion is one of the most serious risks during warmer weather. When your dog overheats, their body struggles to cool down. If not addressed quickly, it can escalate to life-threatening heatstroke. By understanding how it develops and spotting the signs early, you can act fast and protect your dog’s health.
What Is Heatstroke in Dogs?
Heatstroke happens when your dog’s body temperature rises too high and can’t cool down. Unlike humans, dogs don’t sweat through their skin. They mainly cool themselves by panting, which isn’t always enough in hot weather.
Dogs left in cars, walked during the hottest parts of the day, or over-exercised in the sun are at high risk. Flat-faced breeds like French Bulldogs and Pugs are especially vulnerable, along with older dogs and those with thick coats. Recognising the symptoms early could save your dog’s life.
Stage One: Heat Stress
Heat stress is the first sign your dog is struggling. At this stage, they might still look normal to someone unaware, but there are clear warning signs if you know what to look for.
You’ll notice your dog panting more than usual, even if they haven’t been exercising. Their gums may appear redder than normal, and they might seem unsettled or anxious. They could lie down more often or start seeking shade urgently. This is your opportunity to act before it progresses.
Stage Two: Heat Exhaustion
If heat stress continues, it develops into heat exhaustion. At this point, your dog’s body is overheating and can’t regulate itself properly. This is an emergency.
Your dog might start vomiting or have diarrhoea. You may see drooling, weakness, or confusion. Their heart rate will be higher than normal, and they may collapse. Their breathing becomes shallow and rapid, and they may not respond to their name or your commands. You must cool them down immediately and contact your vet.
Stage Three: Heat Stroke
The final stage is heatstroke, and it’s life-threatening. Your dog’s body temperature has risen to a critical point, usually over 40°C. This can cause organ failure, brain damage, or death if not treated fast.
Seizures, loss of consciousness, and a complete lack of coordination can happen during heatstroke. Your dog may appear stiff or have muscle tremors. This is a medical emergency. If you suspect heatstroke, move your dog to a cool space, use water (not ice), and call your vet while cooling them.
What To Do Next
If your dog shows signs of heat stress, exhaustion, or stroke, don’t wait. Take immediate action to cool them safely and prevent further harm.
Here’s what to do if your dog is overheating:
- Move them to a shaded or cool area right away
- Offer small sips of cool water, but don’t force them
- Use room-temperature or cool (not ice-cold) water to wet their fur, especially around the neck, belly, and paws
- Place wet towels on their body, then remove and replace every few minutes
- Turn on a fan or air-conditioning to help lower their temperature
- Call your vet immediately – even if your dog seems to be improving
Even after they cool down, internal damage can still develop. Always get them checked as soon as possible.
Prevention Advice
Preventing heat exhaustion is always better than treating it. You can keep your dog safe by planning ahead and understanding their limits in warm weather.
Follow these steps to reduce the risk:
- Walk your dog early in the morning or later in the evening when it’s cooler
- Never leave your dog in a car, even for a few minutes
- Provide constant access to clean, cool water
- Make sure your garden or outdoor area has shade throughout the day
- Avoid long walks or intense play during hot weather
- Use cooling mats or damp towels at home
- Keep dogs with long or thick coats well-groomed to help airflow
Know your dog’s breed risks too. Short-nosed dogs and those with underlying health issues will overheat faster.
